Fittings

HDPE Fittings Manufacturer

A pipeline is only as good as its joints. We mould and fabricate the full fitting range in-house — butt fusion, electrofusion, flange adapters, stub ends and one-off specials — so the fittings on your job come from the same resin lot and the same quality system as the pipe.

Fittings range

Moulded, fabricated, or electrofusion?

The jointing method usually picks itself from the site conditions. Butt fusion is the cheapest per joint and the strongest, but it needs room to swing a machine and a clean, dry trench — fine for open-cut mains, awkward for repairs and tight excavations. Electrofusion costs more per joint and needs a power supply, but it works in a confined trench and on service connections where butt fusion simply cannot fit.

The moulded-versus-fabricated line falls at DN630. Below it, fittings are injection moulded and carry the same pressure rating as the pipe. Above it, they are cut and welded from pipe, which means they must be de-rated per ISO 4427-3 — a fabricated DN900 tee does not carry the same PN as the DN900 pipe it joins. That de-rating is marked on the fitting, and it is the detail most often missed at design stage.

  • Butt fusion: lowest cost per joint, needs trench space and a machine
  • Electrofusion: works in confined trenches, live repairs and service tees
  • Moulded to DN630 at full pipe rating; fabricated above, de-rated and marked
  • Stub ends plus backing rings wherever HDPE meets valves, pumps or steel
  • Fittings supplied from the same resin lot and quality system as the pipe

Frequently asked questions

Why is a fabricated fitting rated lower than the pipe?
A moulded fitting is a single piece of material formed in one shot. A fabricated fitting is cut from pipe and extrusion-welded, and the welds and mitre angles concentrate stress. ISO 4427-3 sets the de-rating factor by geometry — a mitred bend loses more than a simple tee. We calculate it, mark it on the fitting and state it on the drawing.
Do your electrofusion fittings work with our welding units?
Yes. Each fitting carries a barcode with the correct fusion time and voltage, readable by any standard EF control unit, and runs at 39.5 V / 40 V nominal. If your units log joint data, the barcode is what they log against.
Which flange drilling pattern do we need?
It has to match the valve, pump or existing flange on site, not the pipe. We supply ANSI B16.5 and B16.47, EN 1092-1, AS 4087 and JIS 10K. Confirm the pattern in writing before production — a wrong drilling is the single most common reason an otherwise correct shipment stalls on site.
